We have examined the infrared properties of Re 13 and V346 Nor which excite Herbig-Haro objects 56 and 57 respectively. We provide the first detection of Re 13 in the infrared. In the IRAS Point Source Catlaog Re 13 and V346 Nor are confused into a single source IRAS 16289-4449. We have applied maximum entropy based deconvolution techniques to demonstrate that Re 13 and V346 Nor are distinct far infrared sources. The IRAS fluxes are deduced from the raw scans by taking advantage of the known relative positions of Re 13 and V346 Nor. Both objects emit most of their energy at far infrared wavelengths suggesting that they are at an early evolutionary phase. We estimate Lbol = (50 +/- 10) x (d/700 pc)2 solar luminosity for Re 13 and Lbol(1983) = (135 +/- 8) x (d/700 pc)2 solar luminosity for V346 Nor. This indicates that the stars are at the high luminosity end among the group of sources exciting Herbig-Haro objects. Nevertheless, V346 Nor has a rather low luminosity with respect to its classification as an FU Oriois star.
